UNITED STATES PATENT OFFICE.

REFRIGERATOR CAR.

Application. filed. April 4,

This invention relates to improvements in refrigerator cars.

In the operation of refrigerator cars. at the present time, it customary to locate the drain pipe for the ice box in the floor at a point inwardly of the side wall of the car and also inwardly of the usual underiirame side sill and at the end of the car over the truck. With this arrangement, the molten ice continuously drips onto the truck causing an unsightly slimy condition and unnecessary deterioration oi the truck parts due to increased corrosion.

One object of my invention is to provide simple and inexpensive means to overcome the disadvantages above indicated in pres ent types of refrigerator cars and to assure the discharge or the water from the ice box to a pointoutside and clear of the trucks.

A more specific object of my invention to provide an arrangement of the general character above indicated, which may be used not only on new equipment, but also readily applied as an attacl'iment to refrigerator care now in service without necess tating any change in the car construction oi? the latter, nor any change in the standard drain appliances employed.

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawing forming a part ofthis specification, Figure 1 is a broken, vertical, sectional view, taken transversely of a refrigerator car showing the drain pipe arrangement with my improvements in con- :nection therewith. In dotted lines is indicated the upper portion of one oi the car wheels in. order to bring out the relation of the parts. And Figure 2 is a part plan View, part horizontal, sectional view corresponding to the brokenline 2 2 of Figure 1.

In said drawing, 10 indicates a channel side sill. o1: a refrigerator car underframe, 11 the usual flooring comprised of multiple layers oi planks and 12, the insulated side wall structure,the details of which itis uh? necessary to enter into. As customary in refrigerator cars, the drain pipe is located as clerly illustrated in Figure 1, that is, inwardly of the side wall of the car and in wardly of the side sill and at a point over the car truck. A common form of drain appliance indicated in the drawing which consists of a bowl 13 counter-sunk into a 1927. Serial No. 180,744.

suitable opening 14 cut out from the flooring, the bowl having an annular, upper flange 15, seated flush in the top planking. The bowl 13 has a short pipe section 16 at its bottom end, inclined at a slight angle to the vertical and toward the outer side of the ear, said pipe section being received in a suitable smaller opening 17 in the lower planking of the floor. As customary, a drain pipe 18 is inserted through the pipe section 16 of the bowl, the pipe 18 extending at a corresponding angle and having the upper part 'or inlet end thereof raised an apple ciable distance above the bottom of the bowl, and the lower or discharge end thereof extended downwardly several inches below the floor level. A pivotally mounted cover plate 19 is attached to the bowl 13 and adapted to seat over the inlet end of the drain pipe 18 while permitting access to the latter from the interior of the car when the cover 19 is lifted. The parts so far described are or may be of any well known or desired construction. As will be understood by those skilled in the art, the water will collect in the bowl 13 until the lever rises tothelowermost edge of the inlet end 01' the pipe 18 and will then drip oil oi? the lower edge of the outlet end. With such an arrangement, it is obvious thatthe drippings will fall down onto the truck parts immediately therebelow and keep the latter constantly wet, the drippings spattering as the car is in motion. This causes an unsightly condition of the truck and obvious ly promotes excessive corrosion.

In'carrying out my invention, 1 provide what may be termed an attzmlunent in the form of a spout designatedgenerally by the reterence character A. This attachment is preferably in the form of a casting of approximately U-cross-section. At its upper end, the width of the spout is greater, asindicated at QOand narrower at its lower end as indicated at 21. At its upper end, the spout has the sides united by a rounded end wall,:the upper end of the spout being such that the lower end of the drain pipe 18 may he pro ected tlieieinto in the manner indicated in Figure 1. At its lower end, the spout A is provided with a flange lip 22, the spout being extended through an opening 23, out in the side sill 10 so that the water as it drips oil of the spout will be delivered at a point outside of the side sill and entirely clear of the truck. In the specific tegral ly nier being adapted to be riveted to tl e veb form shown, the spout; is provided ,with in; ormed: flanges. Lend. 25 e-f i '.-.1
